SAVV-BLADE HOLDER.

Application filed May 9,

.Baltimore. in the county of Macoinb and 5 State of lwiichigan, haveinvented certain new and useful Improvements in Saw-Blade Holders, ofwhich the following is a specification.

This invention relates to saw blade holders and more particularly to onethat is adapted to hold a broken hack saw blade.

Vith the present form of hack saw blade holders it is impossibleto use abroken hack saw blade since the broken blade is not adapted to fit onthe pins carried by the yoke arms of the holder. It is well known thata'hack saw blade is very easily broken under any undue strain and as aresult quite a few blades are wasted, but with my device a broken hacksaw blade may be clamped in my holder and the blade may then again beused, thus eliminating a' waste resulting from the use of only anordinary hack saw blade holder.

The object of my in *eution is to provide means t'or quickly andsecurely clamping a hack saw blade to a support. and furthermore. theclamping means is adapted to engage the faces oi the hack saw blade attwo widely separated points and at any place along the hack saw blade..Vith this grip ping means it is possible to grip the blade so as toprevent longitudinal movement of the blade with respect to the supportwhen the saw is in use.

In the drawings:

Fig. 1 is a perspective view of my holder with a broken hack saw bladeclamped therein.

Fig. 2 is a transverse section through holder showing the clampingmeans.

Fig. 3 is a detail in perspective of the support.

Fig. i is a detail in perspective of the clamping plate.

The handle 0- has secured thereon a sup port Z by means of the tongue 0which is forced within one end of the handle as shown in Fig. 1. Thesupport Z) is provided with a pair of laterally extending ears d, saidears projecting substantially 90 degrees from the plane of the support.These ears are each provided at the outer ends with a dl J a and shorter1923.

upwardly extending lip f forming shoulders g and lz respectively.

The clamping plate 2' is provided at each end with notches the saidnotches adapted to engage the narrow portion of the ears (1 and to beslidably supported thereon. A clamping screw 7c is threaded through thesupport and the stud end of the screw is adapted to bear against theclamping plate to force the said clamping plate against the shoulders gand it carried by the laterally extended ears. A saw blade m isadaptedto fit between the clamping, plate 2' and the downwardlyextending liprc and when the clamping screw forces the clamping plate.

i-Ticient pressure may be applied to the ping means whereby the sawblade is 'ltlltllnitl movement with respect to the seem loi y held inplace and prevented front support. It is a very easy matter to disengagethe saw blade trom the holder when it is necessary to remove the sameand another blade may then be quickly inserted anc clamped into place.

lh' ith the use of my holder it is possible to clamp therein a brokenhack saw blade of different lengths. The shoulders 9 provide a pairofwidely spaced points for engaging the outer face of the saw blade, whilethe clamping plate 2' engages the inner "ace of the saw blade betweenthe two widely spaced shoulders g. The clamping screw which bearsagainst the clamping plate to clamp the saw blade in the holder causesthe hack saw blade to be simultaneously clamped at two widely spacedpoints.

Another important feature of this invention is that it enables the hacksaw blade to be used so that it can reach otherwise inaccessible placesor bear against fiat surfaces which cannot be done with the ordinaryhack saw-frame.

What I claim is:

1. A saw blade holder, having in combination a support provided with alaterally projecting arm, a clamping vise supported by said arm, andmeans for clamping the jaws of the vise to hold the saw blade in a planeoffset from the plane of the support.

2. t blade holder, having in (zombie nation a support provided with apair of laterally' extending arms, a pair'ofclainp ing Vises supportedby the'arms in a plane offset from the plane of the support, andmeans-"carried by the support for clamping the jaws of the vises'tosclamp a sawblade therebetween and position the same in a planeoffset from the plane of thesu'pport.

3. A saw blade holder, having in combination a support provided'witli alaterally extending arm, a clamping vise supported by the arniin' aplane offset tromthe plane of the support, and a screw passing throughthe support for" closing. the jaws of the clamping vise to clamp a sawblade therebetween and position the same in a plane off'set fromtheplanfe of the support.

at. A saw'blade' holder having in combination, a support provided with apair of cars having upturned and downturned lips on" the end thereof,said downturned lips adapted to engage one face of a saw blade, aclamping member slida'bly supported between said ears and'arranged toengage the otherface of the saw blade and the upturned lip, and meansfor forcing the said clamping member against the upturned lipscarriedbythe support and'the saw blade to clamp the saw blade betweenthe downturned lips'and the clamping member.

5. A saw blade holder having in combination a support provided with apair of ears having downturned portions for engaging the outer face of asaw blade a clamping member slidably supported by said ears and arrangedto engage the inner face of he saw blade, and means "for "forcin thesaid clamping member against the downturned ear portionseca-rried by thesupport to clamp the saw blade therebetween.

6. A saw blade holder, having' in combinatioi'r a support provided withwidely spaced ears having downturned portions for engaging the outerface of a saw blade at spaced: intervals; a clamping 'plate sliidablysupported on said support and arranged to engage the inner face of thesaw blade intermediate of the down-turned ear portions,--

having in combition's atthe ends for engaging the'outer face of a hacksaw blade, a clamping' ,plate pro vided with notches arranged? to fitover'the said ears, said plate slidably supported thereon, and adaptedto engage the inner face of the hack saw blade, and a clamping" screwcarried by thesupport and adapted to bean against the clamping plate fbiclamping the hack saw blade between the down-turned portions 0! the earsand the said clamping plate.

S; A, saw blade holder, having incombi"; nation, a supporthaving'laterallyextendf ing ear's positioned at substantially clampingplate for binding the saw blade between the downturned ends of the saidlaterally extending ears and'the snide-lamping plate.

In" testimony whereof I atiiX my signature.
